impregnation, resulting in typical amorphous ( v nm− ) vox species. catalysts containing , , and % (w/w) v o were deposited directly from the flame on ceramic foams that were tested for the partial oxidation of o-xylene to phthalic anhydride. the global activity of flame-made and conventionally impregnated...
performed using air as oxidant with ch /o = and a gas hourly space velocity of – nl ch /(g h). the product composition was compared to thermodynamic equilibrium at bed exit temperatures, and any deviation from equilibrium could be explained by temperature gradients. it was found that the presence of co-impregnated...
oxidative dehydrogenation (odh) of propane. depending on vanadia content, different vanadia species were formed. the as-prepared flame-made catalysts showed dominantly isolated monomeric vox surface species for v loadings exceeding even the typical "monolayer coverage" ( v nm− ) of classic wet-impregnated...
